In a small town, elderly Mrs. Gillis, who in a large Victorian home, receives a visit from a man just out of the army. He's seeking a job and a place to stay, and he knew the woman's late son, so she gives him room and board and small tasks to do. Slowly though, he becomes more and more aggressive and paranoid until it's obvious he's a psychopath that wants to get rid of her and take over the house.
